HOSE-COUPLING.

To all whom it may concern Be it' known that we, ALVY B. LEMON and CARLC. GULVIJR, citizens of the United particularly to that class which maybe quickly and easily connected and disconnected.

The object of the invention is to provide a simple and practicalcoupling of this character which may be used upon various kinds of hose,pipes and the like and which is pro-- vided with locking means foreffectively retaining the members in coupled relation, butat the saidtime will enable them to be quickly and easily uncoupled.

Another object of the invention is to provide a hose coupling of thischaracter which will possess advantages in points of efficiency anddurability, is inexpensive to man ufacture and at the same time issimple in construction and operation.

Vith the above and other objects in View, the invention consists in thenovel features of construction and the combination and arrangement ofparts hereinafter more fully described, pointed out in the. claim, andshown in the accompanying drawings in which,

Figure 1 is a side elevation of a hose coupling constructed inaccordance with our invention. Fig. 2 is a longitudinal sectional view.Fig. 3 is a transverse sectional view.

Referring more particularly to the drawings, 1 indicates the annularbody of the female part of the coupling. Formed integral with the body 1at one end thereof is a reduced extension to which the hose or otherconduit is adapted to be connected in any.

opposite points upon each side of the body. These arms 8 are spaced fromthe extension 2 by means of the blocks 9 which may be constructed ofleather, wood or other suitable material. The arms 8 are provided upontheir outer faces with the longitudinal grooves 10 which communicate atone of their ends with the elongated grooves 11 formed in the outer faceof the body. Arranged within these grooves 10 and 11 are the resilientplates 12 having enlarged p ortions 13* formed upon one of their endsfor engagement in the-grooves 11. These plates are held securely inposition by means of the bolts 14 which pass through the reducedextension" 2, through the block 9, through the ends of the arms 8 andthrough the inner ends of said plates. Nuts 15 are then threaded uponthe outer ends of the bolts to securely hold the plates 12 within thegrooves in the arms. The enlarged ends 13' of the plates 12 are securedto the locking plates. 5

by means of the screws 16 which pass through the plates and into thelugs 7. Straps 17 are also secured to the plates 12 by means of thescrews 16 so that the arcuate plates 5 may be readily actuated withinthe groove 4;.

The male part 18 of the coupling is provided upon one end with a neck19, terminating in a beveled flange shown at 20 which is adapted toengage with the beveled faces 21 upon the locking plates 5 when the malepart 2 is inserted within the female part 1, the neck 19 passing betweenthe locking plates and engaging behind the rear end thereof as shown inFig. 2, the annular shoulder 22 engaging with the outer ends of thelocking plates. The annular body portion of the male member 18 isprovided with an enlarged shoulder 23 which is adapted to engage with anannular shoulder 24 formed in the end of the part 1. An annular shoulder25 is formed at the inner end of the body 1 of the female part andarranged at the base of this shoulder is a rubber packing ring 26against which the end of the part 18 is adapted to abut, thus preventingany leakage of water, gas or the like which is to be conveyed throughthe hose or pipes.

From the above it will be apparent that the male part 18 of the couplingmay be readily inserted within the female part so that the annular neck19 will engage between the locking plates 5, said locking plates beingarranged within the annular groove t opposite the neck 19 thuspreventing any longitudinal movement of the part 18. The locking plates5 are normally heldin a locked position by the resiliency of the plates12 to which the locking plates are secured. To release the male member18 the straps 17 are pulled outwardly until the locking plates aredisposed entirely within the groove 4: thus leaving the inner end of themale part 18 free to be withdrawn from the body 1. 7

By the provision of the longitudinally extending arms 8 on oppositesides of the coupling member 1, the coupling may be readily grasped tomove the hose from place to place, said arms afiording convenient handholds to be grasped by the fingers.

From the above description taken in connection with the accompanyingdrawings, it will be apparent that we have provided a simple andpractical hose coupling wherein the male and female coupling parts maybe readily connected or quickly and easily disconnected. It will also beapparent that the device is extremely simple in construction and can bemanufactured at a com 'iaratively low cost.

lVhile we have shown and described the preferred form of our invention,it will be obvious that various changes in the details of constructionand in the proportions may be resorted to for successfully carrying ourinvention into practice without sacrificing any of the novel features ordeparting from the scope of the appended claim.

l/Vhat we claim is The combination in a coupling, of a pair of bodyportions, clamping means at the juncture of the body portions, one ofsaid body portions having grooves therein, arms provided upon said bodyportions adjacent the grooves, resilient plates disposed within thegrooves and engaging one body port-ion and the arms formed thereon, saidarms extending parallel to and spaced from one end of the body portion,said body portion having recesses formed therein, said recesses beingdisposed in registration with alining openings provided in the arms andthe resilient plates, bolts extending through the said alining openings,the heads of said bolts being disposed within the recesses in the bodyportion, nuts disposed upon the bolts and contacting with the resilientplates, and spacing means disposed upon the bolts between the arms andthe body portion, as and for the purposes set forth.

In testimony whereof we hereunto aflix our sigi'iatures in. the presenceof two witnesses.
